APPARATUS FOR MILKING.

SPECIFICATION forming part of Letters Patent No. 673,296, dated April 30, 1901.

Application filed February 4, 1899. Serial No. 704,556. `(No model.)

'To all whom it may concern/1 Be it known that we, GEORG SIEMsGLss, merchant, of Walsrode, near Hanover, and GEORG DASEKING, manufacturer, of Geller Chaussee 179, Hanover, Germany, have invented an Improved Apparatus for Milking, of which the following is a specification.

It has been"observed that milking is more easily carried on if the teats are kept moist and warm. The new milking apparatus takes advantage of this point and effects the moistening o`f the teat and constantly surrounding it with warm air during the process of milking orinducing the low of milk. This air is, moreover, previously purified, so that the milk and the teat come in contact with only the purestair, free from bacteria.

The subject of our invention is a vacuum milking apparatus by means of which the above purposes are effected; and our invention will be described with reference to the accompanying drawings, in which- Figure l is a vertical section of the vacuum and milk-receiving apparatus. Fig. la is a vertical section of a milk vessel, illustrating a modification in construction of the automatic air-valve for controlling the suction. Fig. 2 is a vertical section of the milking apparatus. Figs. 3 and 3 show in vertical section andin two positions a three-way cock employed to control the connection between the primary milk-receiver and the vacuum apparatus and milk-reservoir, as hereinafter described. Fig. 4 is a sectional elevation of connections between the primary milk-receiver and vacuum apparatus and milk vessel, showing a concentric arrangement of the milk-pipe and air-pipe, as hereinafter described. Fig. 5 is an elevation of the` entire apparatus in position for use.

The vessel B is suspended in the milk-res-V ervoir B, and the milk i'lows from it through the valve B/l into the milk-reservoir BC In consequence of this separate vacu lim-spaceviz., the vessel B--it being only necessary to use a relatively small space in which to produce a vacuum, the suction action can be rapidlystrengthened or weakened, and,more over, a closing of the cocks while the milkreceptacle is being fitted on is rendered unnecessary.

To prevent the liquid from overflowing through the pipe c into the pump when the vessel B becomes too full, a valve-lid K, with `a iioat L, is attached. As soon as the liquid comes into contact with the float L it raises it, and the float forces the lid K against the opening of the pipe c. The vacuum then draws the lid so tightly against this opening that it is completely sealed.

The tube or pipe c has a cock c4, and as soon as the liquid is run off this cock is opened, and when the air enters the lid is again drawn back by means of the iioat.

Instead of a valve-lid with a float a cock with a iioat may be used, Fig. la. When the liquid has in this case reached the maximum height, the float L is raised and opens the cock H, so that air enters and dispels the vacuum. The liquid runs off, and the float sinking down closes the cock again.

The primary milk-receiver C consists of two chambers c andm and is connected with the `milk Vessel B by means of the double three-way cock g, so that on turning the cock g the inner chamber c' and the outer chamberm are alternately brought into connection with the vacuum by means of the pipe. In consequence of this the teat e is rubbed and the udder massaged. The Valve arrangement g need not necessarily be a three-Way cock, but any suitable device may be employed. The way U to the inner chamber c' is divided into two ways, the milkway D and the airway p, which are respectively closed by lipped valves d and k. The valve d in the milk-tube D opens away from the chamber c', while the valve la in the pipe p opens toward it. When the way U is connected with the outer air, the air flows through the valve k and the pipe p into the upper part of the inner chamber c' at Z, and consequently some of the milk contained in the cock and the pipe is taken up by it and spurted against the teat. The air thus circulates continually around the inner chamber e. The lipped valve d in the milk-pipe D being turned away from the chamber c prevents the air from passing through this valve into the milk-tube D. Further, this valve, which prevents the outer air from forcing itself into the chamber c from below, compels the outer air to take the way through the air-pipe p and to enter at the top into the inner chamber c'. As the ou-ter air when streaming rapidly against the teat, especially when the teat is moist, pro- IOO introduced into the chamber c. To enable this to be done, the vessel E is provided,

which is connected, by means of the pipe Z, with the port t', Fig. 2, which connectsthe upper port g of the cock g with the outer air. Under the bottom o of this vessel E a lamp 'w burns. In the chamber .fr over the bottom 'v is water or formalin, which vaporizes and produces expansion in the chamber as the passage outward at y is closed by a valve. The safety-valve S prevents the expansion in the vessel E from being to great.

The lamp-casing E takes the form of a lantern, so that light is always at hand, and a separate lantern is not necessary. v

When the cock g is so placed that the port t is in connection with the innerv chamber c', the warm air Hows out of the chamber @c through the pipe Z, the port c', andthe airpipe p into the inner chamber d. Simultaneously outer air flows through the valve y into the` vessel E, corresponding lin volume with the warm air which flows into the chamber c'. The air is puriiied before it enters into the vessel E, so that after the water and formaldehyde-vapor have effected the destruction of the bacteria in the vessel E only pure air can reach the receptaclec'.

In another application, Serial No.` 704,557, led simultaneously with this, we have described and claimed the milking apparatus, including means for applying massage to the udder and teats and the construction of controlling-cock, by means of which the cham bers are intermittently connected with the vacuum-chamber. A

'In the above description of our vacuum milking apparatus it will be understood that it is essential to produce a substantiallyairtight closure orV joint between the primary milk-receiving device C and the udder. To this end the outer wall of the primary milkreceiver C is preferably made of flexible rubber with an inturned and serrated margin at top, as shown in Fig. 2. Beneath this inturned margin is a network c3, of felt, wadding, or other material permeable to air, sur- K rounded by a spiral spring c2, of wire, to proseV duce a massage surface for the udder under the intermittent pressure and` suction or airexhaust operation. An air-pipe o communicates with the outer chamber m, and this communicates by a branch pipe t in one direction with a cock s, opening directly into the vacuum-chamber B and in the other direction with the lower port g2 of the cock g.

r represents a cock communicating with the outer air, which is manipulated in the beginning of the operation to effect intermittent pressure or alternating pressure and suction.

The operation is as follows: At the beginning of the milking operation the upper duct g of the cock g is connected with vacuumreceiver B. The small air-cock r, which is arranged in the line of the lower duct g2` of .As soon as this is the case then turning of cock gis no longer necessary, butl the aircoc'k r is closed, and then by opening the cocks a continuous vacuum is produced in the chamber m, so that the ,udder closes the two chambers fm and c to the outer air. The milk then runs continuously, and the duct g of cock g carries the same into' can B.

What we claim as our invention, and desire to secure by' Letters Patent, is-

1. In a milking apparatus the combination of a milk-receiving chamber adapted to inclose the teat, air-exhausting apparatus connected therewith, a lateral opening into the upper part of said chamber, an air-pipe connected with said lateral opening, means for injecting air into the chamber through said `pipe and lateral opening and means for introducing a portion of the milk into said injecting-pipe, whereby a jet of milk is thrown against the teat during the milking operation,

.as explained.

2. In combination with a milk-receiving `chamber adapted to inclose the teat,- an airchamber c pipe D for conducting milk from the lower part thereof, air-pipe p connecting with the upper part thereof, check-valves d :and k to prevent the reliux of fluids in said pipes, means for injecting milk into the airpipep and an air-forcing apparatus to inject such milk against the teat as explained.

4. 'The combination of the milk-receiving cham-ber c milk-pipe D conducting therefrom, a suitable exhausting appliance connected with said milk-conducting pipe, and an airpipe passing through the milk-pipe D and connected with the chamber c' whereby air delivered to the chamber c' through the pipe p is warmed by the flow of milk around said pipe as explained. p y

5. The combination of the milk vessel B milk-pipe D delivering therein, air-exhausting pipe c connected with the vessel B through a valve-guarded opening, and a float L controlling said valve so as to prevent overflow of milk through the exhaust-pipe, as explained.
